ALBERT OHRISTEN, OF NEW YORK, N, Y., ASSIGNOR TO CONSOLIDATEDSHIPBUILDING CORPORATION, OF NEW YORK, 1\T. Y., A CORPORATION 0F NEWYORK.

SHIP-VENTILATOR.

Application filed June 6, 1919.

To all whom t may concern:

`Be it known that I, ALBERT CHRIsTEN, a citizen of the United States ofAmerica, residing at New York city and State of New York, have inventeda new and useful Ship-Ventilator, of which the following is aspecification.

My invention relates to ship ventilators, the object being to providemeans to prevent the driving of rain or spray through the ventilatordown in the cabin, engine room, or below decks.

In the drawings:

Figure l is a vertical section partly in elevation of my improvedventilator.

Fig. 2 is a relatively enlarged sectional view of the rear side of theventilator near the deck.

l represents the main body of the ventilator which is of conventionaldesign having the usual round or oval open front into which air drivenby movement of the vessel.

The body portion also has the usual downwardly extending tubularportion, or neck, which acts to conduct the air down below decks.

Any suitable means may be provided for mounting the ventilator on thedeck or cabin. One well known means comprises an annular deck flange 2around a deck open-l ing into which flange the neck of the ventilatormay be screwed.

lVithin the ventilator I secure means which serve to catch any waterwhich may run down the inner wall of the ventilator,

' which water, so caught, will drain out, in-

stead of being permitted to drip into the cabin. In the drawing thiscatch-water device is in the form of an annulus 3a secured within theneck of the ventilator in such a manner as to forma trough 4, which ispreferably annular. The annulus 3 is relatively contracted at its upperportion so that its diameter is somewhat less than the diameter of theadjacent portion of the ventilator neck. The lower part of said an nulus3a is expanded so as to fit tightly into the surrounding wall of theventilator neck, wherein it is secured, in such a manner as to make awatertight joint. The manner of securing the annulus 3a within theventilator body is immaterial so long as a proper Specification ofLetters Patent.

joint is effected. The front portion of the annular catch-water device3a is made higher than the rear portion so as to check a driving spray.

5 is the drain outlet for the lower part of the trough 4E, said outletbeing preferably at the rear side of the ventilator neck so that therewill be no drafty of air to interfere with the free drainage of wateraccumulating in the trough. Of course the particular location and numberof the drain outlets 5 is immaterial, broadly speaking, but I prefer toarrange them in such a manner as to not interfere with free drainageaction.

Operation: From the foregoing, it will be seen thatas the boat or vesselupon which the ventilator is mounted drives ahead, any rain or spraywhich enters the open front of the ventilator will enter at such anangle as to strike against the front wall of the part 3n and the rearwall of the part l, down which walls it will run until it enters thetrough 4L whereby its further descent through the ventilator will bechecked and from which it will readily drain.

It should be understood that I contemplate that various changes indesign and details may be made without departing from the spirit andscope of this invention.

I claim l. In a ventilator of the character described, a main bodyhaving an air receiving4 opening at the front and a descending neck, anannular catch water device secured within the descending neck andforming a gutter around the inner wall thereof, the front wall of saiddevice toward said air-receiving opening being higher than the rearwall, said gutter having a drain outlet.

2. In a ventilator of the character described, a main body having anair-receiving opening at the front and a descending neck,

ALBERT GHRISTEN.
